This study was conducted with the aim of determining the genotypes of the leptin gene and its relationship with total weight
gain rates and the daily, relative and specific growth rates in 66 samples of common carp (Cyprinus carpio L). Results of
Sequencing and Single Nucleotide Polymorphism-SNP showed three genotypes at site of 2092 CC, CT and TT, and distribution
ratios of genotypes were 4.55, 12.12 and 83.33%, respectively, and the differences between these percentages were highly
significant (P < 0.01). The allelic frequency of the allele was 0.11 in C genotype, while the allele frequency of T was 0.89.
Results showed that there were no significant differences between the genotypes of the studied growth traits, the total
weight gain rates in the genotype CC reached 45.66 g/fish, and in the genotype CT 42.25 g/fish, while in the genotype TT was
36.30 g/fish. The daily growth rates were 0.65, 0.60 and 0.51 g/day in the genotypes CC, CT and CT, respectively, and the
relative growth rate was 47.29% in the genotype CC, and 44.58% in the genotype CT, while it was 39.87% in the genotype TT.
The specific growth rates were 0.55, 0.52 and 0.46% /day in the genotypes CC, CT and TT, respectively.
